doar 2 and an ash door 3. The fue dom 2 communicates with the ginie 3'of the vice, and it will' be mtfsd by refmenca t0 Fig. of the drawingUhm', ihe gmt@ bams *With "she above, and oher obj'ecs in View 'which'will @ppea as the descrptiompww (lavica is a u'mel sha Sidmouth 9 ofiypipe' membsr 10..-f-"h1s-p1pe member@ has a,

By this arrangement it will be noted. vthat when the fancontained. within the casing 14: is revolved the productsn of combustionpassing through the pipe mein- 4 bers 5 of the boiler L'lare drawn throuh the ,pipe sectionl() downwardly throng the casing 14: and from thence.to the ash pit. directly below the grate and it will be fu-f' ther,sunderstood that the air from the fan,

will fnot onl add tothe combustion o the fuel upon t e grate 3 but willreburn the! products forced through the. pipe 17. I

Positioned within thecasing 1'2 and supporte-d thereinthrough the mediumof suitablebrackete 18 is an auxiliary Water re*- ceiving tanl 19. Thistank 19 has its upper extremity provided with an inlet pipe 20 and hasits lower portion provided with a feed pipe 2l. This feed p1pe21communieates with the boiler d and it will be readily noted that as theheated' products of combustion are passed 'through the casing 12 v the'Water Within.l the tank 19 will be parl tially heated, so that steam maybe generated within the boiler in a short length of time.

Connected with the boiler'd is a pipe mem.-

ber 22. This pipe member has a suitable comparatively valve 23y and `theextremity of the said pipe vmember 22 projects Within the casing-,12

directly belovvthe tank 19. The end of this projecting portion isprovided with a per-` forated nozzle 24, and it will be noted that esthe steam is passed through the pipemem- 1oer 22 into the casing 12 anddirectly below the tank 19, the said steam will not only assist inheatingv the water Within the'tank 19but will edectively dampen thesparks of with the fuel upon the saidgrate. The pipe member 25 isprovided with an vordine damper26, as is the pipe extension 17 leaindirectly to the as pit 18.

he products of' combustion `flowing throughthe conduit 10 and into the'casing nosoese' the nozzle' 2e, 'and distributed by the lower` end ofthe tank 19 and a einst the lower end of the casin thereby e ecting anintimate 'fjniirture of t `e roducts of combustion with Athe vsteamwhere y the density of these prod- 'ucts is increased so as to promotethe final peesagethereo to the furnace. It will thus e for a practicalnovel coperation of a Water preheatng means and the smoke consumingmeans.

From the above description, taken in connection with the accompanyingdrawings, it will be noted that l have provided a comparatively cheapand. extremel vice' for the purpose intendedy,r may be attached to anyfurnace of the ordinary construction and. one which will perform thefunctions for 'which it is intended with ease and accuracy. K

`Having thus describedv the invention what is claimed as new is`:- Y y Asmoke consumer comprising in combinationwith al furnace and boiler, aconduit adapted to' receive products of combustion from the furnace, a.Water tank, a cylinder surrounding said water tank and having a conicalend extending above said tank and connected with said conduit; anexhaust conduit connected with the lower end of said cylinder, means forreturning products of. combustion passing through said c linder to thefurnace under pressure, en in et and outlet pipe connected with saidWater tank, a steam nozzle located in said cylinder adapted to directsteam against the bottoml Iof said Water tank, said Water tank beindisposed concentrically in said cylinder an providing an annular space,the bottom of the Water tank serving to spread the steam to separatethe' downfiowing roducts'of combustion, whereby the speci c gravityof'said products will be increased.

seen that the construction shown provides simple de"-V one which Intestimony whereof I aflix my signature A in presence of twowitncsses. A
